"Will North Korea Really Go Ahead with a Nuclear Test?" by Takayuki Kanamori for Mainichi Shimbun

ONN senior analyst Katsuhisa Furukawa shared his assumptions on DPRK's Punggye-ri nuclear test site.

"Katsuhisa Furukawa, a former member of the expert panel of the United Nations Security Council's North Korea Sanctions Committee and a senior analyst for the Open Nuclear Network, which analyzes satellite images of the Punggye-ri nuclear test site. With their cooperation, we overlaid past satellite images and compared changes at the Punggye-ri nuclear test site and the status of building restoration. In the article, four images with white circles in the center can be checked by moving the cursor to the left or right to see changes in the nuclear test site and the restoration status of the building.


Furukawa, who analyzes satellite images, said, 'Between the tunnel explosion and early December 2021, Punggye-ri was largely abandoned.' Even in satellite images, the presence of people and traces of movement can sometimes be confirmed. Every winter, it snows and piles up, and satellite images are said to be dyed pure white.


According to Furukawa, even during this time, in North Korea's Yongbyon, where many nuclear-related facilities are concentrated, road construction and construction of new buildings and renovations were progressing in each area, including the living quarters of scientists."
